We can also use these tools to look at the way that physical obstructions and the path/road network itself impacts in greater detail. Centroids in this case in Dunbar have been placed along the Mail Line Railway at 3 underpasses, more less equidistant (there are 2 others ).
Even from those central points access to services would be restricted, due to distance. Access to blue and green space is more than 10 minutes away. This function is calculated using a theoretical walkability algorithm based on openstreet map.
